Discussion Also known as: common daisy, European daisy, lawn daisy. This plant is considered weedy or invasive in some locations; it recovers quickly from mowing. It is thought that the name "daisy" is a corruption of "day's eye", because the whole head closes at night and opens in the morning. Daisy is also a common girl's name and is a nickname for girls named Margaret, after the French name for the oxeye daisy, "marguerite".
